Very slow Corona renderer start

[bango74]

Hello, I'm having a problem for two days, a problem concerning the rendering phase. Specifically if I cast a crown view, any view, the initial phase is very slow as if it were a large file, but then again, this problem comes with either HD or LD images, either with small or large files.
Honestly I do not know how to intervene, I tried to upgrade version of the crown to beta2, to update the beta1 but no positive result.
I hope there is a solution because the work has slowed down considerably, even using IR the same situation happens to me.
Thanks Roberto.

P.S. I forgot to say that once the rendering started then everything proceeds normally.

I was doing tests to understand why this problem occurs to me:
So, with Vray everything goes smoothly, even using heavy scenes, so I exclude that the problem is hardware, but with Corona I noticed that while rendering light moloto scenes you eat 6-7 GB of memory.

I've tried astral projection but it didn't work.
I once was able to leave my body and walk around. Well, I was high, but I still think it was a real experience.
Tonight I might try far-seeing, but I didn't know if it'll work. So, have you Scene open and I will tell you the solution the next day.(if my attempt is sucessful)

Nope, according to your posts, I'm perfectly right here.

Don't forget: answer coming tomorrow

Beyond the unnecessary comments, nobody has happened to this situation?
I am interested in understanding if it is a problem already rediscovered by someone, to arrive at a solution to this problem that is penalizing me and not a little.

The spirits have spoken to me: "Post a picture or even better a scene file or the mortals will have no clue..."

In all seriousness, we would need more information. Is this just one scene, or every scene? I am not sure what is meant about the "size of the image" - is this the resolution you are rendering to, or does it refer to texture maps used in the scene? Are there any plugins used in the scene? An example image of what is in the scene would be useful, but best of all would be the scene itself for testing. What stage is Corona at when it is running slowly (there should be a message on whether it is parsing geometry etc)? Which version of C4D is it?

The more information you can provide - and always, best of all is the scene (the private uploader can be used if you can't share it publicly, https://corona-renderer.com/upload)  - the better we can understand and diagnose any problem.

Thanks!

Fortunately I managed to solve the situation.
Thank you so much Tom ...

Hi bango!

Good to hear! If you have time, could you share what turned out to be the problem? It may help someone else who runs into it - or would help us give people some pointers if they run into something similar. I hope the solution was one that didn't require any major changes to the scene etc.

Thanks!

Is the mortal willing to share his wisdom?

[romullus]

@Eddoron, i think it's enough. Don't act like a troll.

[Eddoron]

I was not trolling, it's just not that easy to get rid of the spirits.

Trolling is the art of making an innocent, ambivalent comment and thus giving one enough rope to hang himself.

So, therefore, I was just channeling.

[bango74]

Yes certainlyTom.
I did not immediately explain the resolution of the problem just because it was not a problem attributable to the crown, a series of tests made at the time when I was presented to the problem I had mistakenly doubted the crown, but in reality the cause was I.
In the sense that I made chaos with preferences in the film texture directories causing this slowing down in the initial stage of cinema.
Sorry if I disturbed for no reason, I thank those who tried to help me.Then I did not want because it is definitely his goal in this forum but I want to spend only one word for this user who in his speech does everything but help the forum, I I address not to him but to the administrators, what is a character like this doing here?

[Eddoron]

If you looked through my past posts, you'd see that the vast majority of them were helpful and led to the solution of many problems.
Aside from mostly theory in animation and programming, I know C4D inside-out and backwards.

I'm just sick of answering the same useless questions over and over again.
Especially those with a poor description and not even providing a picture or a scene file.

What I was trying to do was to hint at you that more information is needed.
You didn't get it.
This was an exception and sadly it wasn't worth the time.

I'll stick to only answering questions that are worth answeríng, again.

TY for sharing the solution! Not a problem that it was thought to be Corona at first - often good to hear what the actual problem was though, just in case there's anything that can be made better, and in case anyone else runs into the same thing and can look in the same place for the cause / solution :) Cheers!

Are you tired of answering? Why who asked you?
I do not look into your posts because I simply do not care to know anything about you, I'm just a simple user who still has much to learn and I try to do it with the help of the various forums, and with what little I've learned until now if I happen to be able to help a user I do it without being a fool like you do.
Conclude by saying that here as in other forums there are users with square balls that sometimes with a lot of humility lend themselves to give explanations to those who know less, humility, what is missing to you that you are a simple user as there are thousands .
Bye ...
You can also close the post, thanks TOM.

Let's not let things get there. We're better than. Yes this is an open forum and users have the freedom of speech. But keeping things to the topic is the point of it all. Deviation is understandable, but let's not go too far. Mmkay

OK, well. This thread has gone in an odd direction, but I'm seeing something similar.

I thought I was having this same issue with my outdoor scene and Shadow Catcher. If I rendered in the VFB or the C4D Picture Viewer, the first frame would take 13:30 sec to even show any part of the image. After that it went quickly. This same scene with just hitting render in the viewport took :12 sec. Huge different when working.

My solution was to restart C4D which worked once. Now it does it all the time. Any other ideas?

****EDIT****  OK so I found what was causing this slow down for me. Recently, I discovered that an old plug-in for C4D was updated for at least r17. It's called Roll-It, a very hand Python script that used to use for simple car tire rotations. Simply apply the tag to each wheel and move the parent object. Roll-It rolls the wheels at the proper speed. Super simple, BUT I couldn't get real-time feedback and that 15 min render time even with the tags disabled. I just deleted the tags and boom, rendering back to normal. Not sure if this is an issue with Corona or the plugin, but thought I should mention it anyway. Maybe there could be issues with other Python scripts and Corona. Here's the link:
